Hi, I need help.
I thought this power supply is truly adjustable, but I don't understand, is it? I've assembled it, the output voltage is always 17V , almost same as on C5. RV1 doesn't adjust anything.
Could you help me please?
Should it be adjustable?
i want ask how to get 3vac to 12vdc?
show the exact fig of ferro-resonant power supply
